FREDERICK COOK, OF TAYLORVILLE, ILLINOIS.

HARVESTER.

SPECIFICATION forming part of Letters Patent No. 354,397, dated December14, 1886.

tNo model.)

To all whom t 'in/ay concern:

Be it known that I, FREDERICK Cook, a citizen of the United States,residing at Taylorville, in the county of Christian and State ofIllinois, have invented certain new and useful Improvements inHarvesters, of which the following is a specification, reference beinghad therein to the accompanying drawings.

My invention relates to improvements in harvesters of that class knownas low-down liarvesters, and is designed to produce a machine that maybe lowered or raised in a vertical direction to adjust the cuttingapparatus for heading or for cutting different lengths of straw, toobviate the excessive elevation of the grain to carry it over thedrive-wheel. The peeuliarity ofconstruction also enters into theinvention.

The above object, as well as the construction of the device, is setforth below in the description, reference therein being had to theanneXed drawings, in which- Figure l represents a perspective view -ofthe harvester; Fig. 2, a plan view of the same; Fig. 3, a rear elevationwith the reel and drive-wheels removed; Fig. 4, an elevation of thegrain end of the platform; Fig. 5, a detail elevation of one of thedrive-wheels, and Fig. 6 a detail elevation of the front caster-wheel.

The machine is provided with two drivewheels, A and B, arrangedpreferably at the rear of the frame, but which may be placed at anyconvenient and practical point where the conveyer o'f the bindingapparatus will not pass over them. One wheel may be used in place oftwo. Each of the wheels is loose on the axle O and carries it in onedirection only by means of clutch D.

Pulleys E, carrying pinons Fform bearings for the shaft or axle C. Thepinions F engage with racks G, secured to projecting thereon, with itspawl l and its connections to the small thumblever at the upper end ofthe hand-lever O, serve to operate the said shaft. A detaining-pawl, R,pivoted to the frame, prevents the backward turning of the shaft Kduringthe reverse motion of thelever O, and this pawl is operated todiscngage with the wheel N by means of a foot-lever, S, secured on thebridge T of the machine, in proximity to the seat.

Chains or ropes U pass from the pulleys E to the drums L and serve toturn the said pulleys so as to elevate the rear of the machine,

the lever O being used for the purpose, while the disengagement of bothpawls from thef `the upper arm con nectedv to the chain or rope .X, itis evident that a rearward motion of the said rope will depress thewheel and raise the grain-receiving platform, while the slackening ofthe said rope will allow the said plat-form to descend by gravity.

On one end of the main drive-shaft is a sprocket wheel or pulley, B,fromwhich a chain or belt passes to a sprocket wheel or pulley, C', on ashaft, D', journaled in the frame of the machine. The wheel O turnsloosely on its shaft, and by means of a clutch, E', carries it in onedirection only. One portion of the clutch is annularly grooved and issplined to the shaft to permit a longitudinal travel. A spring-arm, F',with one end resting in the said groove of the clutch, keeps it normallyengaged with the pulley or wheel C', while a lever or pawl, G', pivotedin the frame and connected to a shaft, II', extending to near thedrivers seat, so as to be conveniently operated by him, disengages theclutch from the pulley or wheel C', and so stops the mechanism withoutstopping the machine. The shaft IOO Izl' is shown in the drawings as arock-shaft, with the upper end so formed as to engage with a catch, I',on the bridge T when the clutch E is thrown out of gear.

On the interior of the frame the shaft D' carries a bevel-gear, whichoperates a short shaft, K', actuating the binding mechanism.

The binding mechanism, which may be of any approved form or pattern, isnot shown in the drawings, as it forms no part of the invention andwould only serve to confuse.

The shaft D' carries at its inner end, beyond the inner frame beam, H, abevel gear-wheel, L', which engages with a bevel-pinion on and givesmotion to a shaft, M', journaled to the frame, and which carries acrank, N', giving a reciprocatory movement to the cutterbar by means ofa pitman, O. (See Fig. 2.) The gear L' also operates a shaft, I2', whichpasses through the rear of the frame and there carries a sprocket-wheelor pulley, R'. From this pulley the chain or belt passes to a wheel, S',at the end of one of the platform-carrier rollers, thence upward to awheel, T', on the reel mechanism driving-shaft U', thence downward to awheel, V', on one of the elevator-rollers, and thence over the loosepulley W' to the said wheel R'. A cog-wheel or pinion, X', on the rollercarrying the wheel V engages with a cog-wheel, Y', on another of theelevatorrollers and serves to operate the same. (See Figs. 2 and 3.)These various rollers, except those belonging to the platform-carrier,are journaled in the uprights support-ing the bridge T. The shaft U'extends longitudinally under the bridge, closeup to it, out of the wayof the elevatorcarriers, and projecting beyond the nprights in which thesaid rollers are journaled is there provided with a gear-wheel, Z',which intermeshes with one on a short transverse shaft, A2, projectingbeyond the sides of the bridge. The projecting portions of the saidshaft form a pivotal bearing for the reelsupporting frame B2.

The front of the machine is supported on a casterwheel, P2, journaled toa sector-plate, R2, which in turn is pivoted at its center to a post,S2, which turns in its bearings, so as to allow a lateral movement ofthe wheel P2. The curved edge of the sector-plate is formed into a rackand passes through a slot in the post. A combined pinion and pulley, T2,isl

journaled in thepost above the sector-plate. In the frame-work of themachineabove the pulley T2 is a pulley, U2, on a s hort shaft carryingalso a worm-gear, V2. A chain or wire rope connects the two pulleys. Ashaft or rod, W2, with a handle near the drivers seat and a worm at theother end engaging with the gear V2, is journaled on the machine, andserves as a means whereby the mechanism controlling caster-wheel isoperated, and the front of the machine raised or lowered at will. Themechanism above described is clearly u shown in Figs. l, 8, and 7.

By reference to`Figs. 2 and 3 it will be seen that the grain-receivingplatform is hinged to the frame at X2 in the front and Y2 inthe rear. Byremoving the wind-board Z2 and the bolt A3 from the rear and the bolt Bfrom the front the entire platform may be turned up so as to-restagainst the bridge, the reel having been rst thrown as far to the frontas possible. By this arrangement the transportation and shipment of themachine through narrow places and convenience for storing is greatlyfacilitated.

In the foreground of Fig. 1 is shown an auX- iliary aXle, which isdesigned for use when it is desirable to move the machine from place toplace, and is secured to a position under the front of the main frame ofthe machine by a king-bolt passing through a socket, C3, on the frameand a similar socket on the said axle. The grain and caster wheels arere moved from their journals and placed on the auxiliary axle. Thepurpose of the axle is to provide a wide support for the front of themachine when it is transported, as the grainreceiving platform is thenraised and the grainwheel would no longer partially support the machine,and the front would be supported by the caster-wheel only, and theliability of the machine tipping over greatly increased. By placing theaxle as described the said grain and caster wheels are utilized and asecure support obtained. A tongue, D3, is removably secured to the frameby flexible couplings, and may also be attached to the axle when themachine is transported. As the front casterwheel sustains the front ofthe machine when in operation, and the tongue is flexibly connected tothe frame, strain on the horses necks from the weight of the machine isobviated.

In transportation the two drive-wheels are used, while in cutting andbundling the grain one will do, and both may be used. All the grain iscarried under the bridge before being delivered to the binder, and theelevation to which it is carried is comparatively small, thereby makingthe power necessary for the operation proportionally less.

The operation is clearly apparent from the foregoing description.

As the invention is not conned .to the specie construction nor the eXactlocation of the various parts as herein described, and shown in thedrawings, and as it is not intended toA limit the claims by placing atoo restricted interpretation upon the above specification, the right tovary the machine and its parts consistent with the spirit of theinvention and its novelty is reserved.

The reel and mechanism connected there with, as shown in Fig. l of thedrawings, forms no part of this invention.

I claim-' 1. In a harvester, a platform vertically adjustable on thedrive wheel or wheels and on the grain-wheel simultaneously and on afront supporting wheel independently, combined with means, substantiallyas specified, whereby the several adjustment-s are effected,substantially as described.
